IIAROLD E. HONDERICH,

INVENTOR "MAM ATTORNEY PALLET This invention relates to work-supporting pallets utilized in association with a lift truck for the moving and storage of products of various types.

Concepts of the present invention provide a pallet of lightweight construction which utilizes the strength of channel section members even though formed of relatively thin material or sheet members, desirably of aluminum or light alloys; and the inventive concepts also provide a desired economy of construction and assembly.

According to the inventive concepts of the pallet of the present invention, a plurality of channel members are tackwelded along their adjacent side-edges, maintaining the members in an assembly in which the intermediate channel'panels cooperate to form the overall palletdeck, and the side panels provide the vertical support legs therefor, supporting the decking in a position high enough to receive the lifting forks or prongs of the associated material-handling vehicle. Transverse strips reinforce the assembly.

The above description is quite general and introductory; more specific details, components, and concepts of the overall invention appear in the following detailed description of an illustrative embodiment thereof, taken in conjunction with the accompanying generally diagrammatic drawings, in which:

FIG. 1 is a pictorial view of a pallet according to the illustrative embodiment, portions of one of the reinforcing strips being shown broken away for clarity of presentation of other components;

FIG. 2 is a top or plan view thereof, in considerably smaller scale;

FIG. 3 is a front view thereof; and

FlG. 4 is a vertical cross-sectional view thereof, being taken generally as indicated by either of the section lines 4 of FIG. 2.

As shown in the drawings, a pallet according to the inventive concepts is shown economically formed from three longitudinal members 12, which may be and desirably are identical, and which are disposed in side-by-side relationship, as shown.

Each of the pallet-forming members 12 is shown formed of a generally channel-type cross section, generally of inverted- U-shape, providing, as viewed from the end thereof, a central horizontal panel 14 and at each lateral side thereof a vertically-disposed supporting panel 16, the lower end of each vertical panel 16 being turned horizontally inwardly a short distance to provide a stiffening flange 18.

It will be observed that the central panels 14 of the three members 12 cooperate to provide the horizontal work-supportingsurface or decking of the pallet.

The assembled relation of the three panel-members 12 is maintained partly in the embodiment shown by tack welds 20 provided along adjacent side edges of contiguous panel-members 12, as shown along both the top and bottom junctions of side panels 16 with top panels 14. The assembled relation is shown also provided partly by supporting members now to be mentioned.

The vertical panels 16 cooperate to provide four vertically disposed support members, in the overall assembly.

Supporting members are shown extending transversely of the assembled pallet-members 12; and as shown, the support members include a front and a rear strip 22, of angle or L- shaped cross-sectional shape, and a central strip 24, of flat cross section. These support members 22 and 24 are secured to the lower portions of the panel members 12, as by tack welding 25; and they both help to maintain the assembled relation of the panel members 12 and maintain the general flatness of the assembly in use.

The rlpstanding wall 26 of each of the strips 22 is of a relatively short height in comparison to the height of the vertical pallet-panels l6; and the opening 28, between the upper edge of vertical strip-wall 26 and the lower face of horizontal palletpanel or decking 14, provides the accommodation or receiving opening for the prongs or forks of an associated lift truck (not shown).

The front and rear support strips 22 may be and desirably are identical, and the front and rear faces of the overall pallet 10 are thus of identical shape.

It is thus seen that a device according to the inventive concepts provides a desired and advantageous pallet, which achieves the dual advantages of both lightness of weight and economy of production.

Accordingly, it will thus be seen from the foregoing description of the invention according to this illustrative embodiment, considered with the accompanying drawings, that the present invention provides a new and useful lightweight pallet, having desired advantages and characteristics, and accomplishing its intended objects, including those hereinbefore pointed out and others which are inherent in the invention.

Modifications and variations may be effected without departing from the scope of the novel concepts of the invention; accordingly, the invention is not limited to the specific form or arrangement of parts herein described or shown.

I claim:

l. A pallet formed of horizontal work-supporting panel means, having extending downwardly from spaced locations thereof vertically disposed support members which support the said panel means above the associated supporting base upon which the pallet is supported, thereby accommodating the generally horizontal lift members of an associated means for lifting and/or transporting the pallet, in a combination in which:

there are provided a plurality of panel members, each of a generally inverted-U channel shape when viewed in transverse cross section;

there being holding means provided which hold the panel members in side-by-side relation in which the intermediate panel of each of which members cooperates to provide one section of the said overall work-supporting surface; and the other panels of each of the panel members are disposed vertically and cooperate to provide the said vertical support members, the said pallet and its vertical support members accommodating the insertion of said associated means from laterally outwardly of the pa]- let inwardly of the periphery of the pallet and within the space between the associated supporting base and the said horizontal work-supporting panel means, said space being provided by the vertical height of said vertical support members provided by the channel shape panel members.

2. The invention as set forth in claim 1 in combination in which:

the lower edge-portions of each of the said verticallydisposed panels are formed to provide an inwardly-extending stiffening flange.

3. The invention as set forth in claim 1 in a combination in which:

there is provided welding along contiguous edges of the panel members for holding the said panel members in the said assembled relationship in which they cooperate to provide the pallet.

4. The invention as set forth in claim 1 in a combination in which:

there are provided support strips extending laterally with respect to the axis of the said panel members, and lying adjacent the base thereof.

5. The invention as set forth in claim 4 in a combination in which:

there are support strips at each end of the said panel members, these support strips being of a general L-shape when viewed in cross section, one flange of which underlies the lower edge of said vertically-disposed panels and the other flange of which is disposed vertically, the said other flange being substantially less in height than is the height of the said vertically-disposed panel member panels, and the said associated lift members are accommodated between the upper edge of said other flange and the lower surface of said intermediate panels.
